C# - Rounding Down to Nearest Integer

Question

I have a C# app that is calculating some numbers. I need to round down.

var increment = 1.25; var result = 50.45 - 23.70;    // equals 26.75 int interval = difference / increment; // result is 21.4. However, I just want 21 

I have to get the interval to an int. At the same time, I cannot just use Convert.ToInt32 because of its rounding behavior. I always want the lowest whole number. However, I'm not sure how.

Answer 1

Just try this..

 int interval = Convert.ToInt32(Math.Floor(different/increment)); 

Answer 2

Use the static Math class:

int interval = (int)Math.Floor(difference/increment); 

Math.Floor() will round down to the nearest integer.
